Use PKG_SEARCH_MODULE() to detect json-c library,
otherwise the search fails, if both json-c and json
are not present in pkg-config database.

The ulog api is intended to be used by procd, fstools, ubox etc. to provide
a generic logging api for early boot messages and automatic switching between
syslog / kmsg / stdout depending on the way the process is executed.

It turns out that mach_absolute_time() is not monotonic at all. While
at it, convert the CLOCK_REALTIME implementation to using
clock_get_time() as well.

It can be used to fill caller-specified buffer with data already in
ustream read buffer. Useful in the following use pattern.
int available = ustream_pending_data(s, false);
if (available >= sizeof(struct msghdr)) {
struct msghdr h;
ustream_read(s, &h, sizeof(h));
}

Otherwise some flags like USOCK_NONBLOCK wouldn't work as expected
(O_NONBLOCK affects connect behavior).

Though currently jshn is more a one-shot data transformation tool and
won't leak much memory in its lifetime, people may use it as example
code, so do it right.

The cmake logic is wrong (E.G. PKG_CHECK_FOR_MODULES fails unless all
modules are found), and the legacy libjson.so name is also used by the other
libjson (http://sourceforge.net/projects/libjson/) which provides an
incompatible API, so just drop it.

Add a new helper function usock_port() which converts the given numeric port number
into a string using a private static buffer. This way a calling application can
conveniently use numeric port arguments without having to convert them before:
int fd = usock(USOCK_UDP, "example.org", usock_port(80));

Quote the output of the "jshn -r" backtick expression to prevent the shell
